Edelar Fecteau 1877 Massachusetts

Looking for parental information on my Great grandfather Edelar Fecteau DOB 4/13/1877 in Masachusetts (from WW1 draft registration) Date of death Sept 1967 in Haverhill MA. He married Ellen Mary Richards born in 1878 in Vermont. They had 3 children Dorothy C, 1904-2004 (my grandmother) Edward B and Richard C. I cannot seem to find any info on him. He shows up in the 1910 census in Winchendon MA at the age of 31 which is where the children were born, as Edgar Fecteau and in the 1920 census in Haverhill MA as Edelei Fecteau. According to the census records, his parents were born in Canada. Any info out there would be appreciated.
